 ### Improvements
+
+* (logging) [\#8072](https://github.com/cosmos/cosmos-sdk/pull/8072) Refactor logging:
+  * Use [zerolog](https://github.com/rs/zerolog) over Tendermint's go-kit logging wrapper.
+  * Introduce Tendermint's `--log_format=plain|json` flag. Using format `json` allows for emitting structured JSON
+  logs which can be consumed by an external logging facility (e.g. Loggly). Both formats log to STDERR.
+  * The existing `--log_level` flag and it's default value now solely relates to the global logging
+  level (e.g. `info`, `debug`, etc...) instead of `<module>:<level>`.
 * (crypto) [\#7987](https://github.com/cosmos/cosmos-sdk/pull/7987) Fix the inconsistency of CryptoCdc, only use `codec/legacy.Cdc`.
 * (SDK) [\#7925](https://github.com/cosmos/cosmos-sdk/pull/7925) Updated dependencies to use gRPC v1.33.2
   * Updated gRPC dependency to v1.33.2
   * Updated iavl dependency to v0.15-rc2
 * (version) [\#7848](https://github.com/cosmos/cosmos-sdk/pull/7848) [\#7941](https://github.com/cosmos/cosmos-sdk/pull/7941) `version --long` output now shows the list of build dependencies and replaced build dependencies.
